Right. Also, there are already too many amdgpu module parameters, we
should try to remove some rather than adding new ones for every little
thing that could be tweaked. :)

One possibility might be to optionally allow passing multiple values to
lockup_timeout, e.g.

 amdgpu.lockup_timeout=10000,0

The first value would need to have the same meaning as now for backwards
compatibility.
